Problem

A class B complementary push-pull output stage is supplied from rails of

\pm18\,\mathrm{V}

and drives a resistive load of

6\,\Omega

. At a particular signal level the peak output voltage is

V_p = 12\,\mathrm{V}

. Find the output power, the power drawn from the supplies, the efficiency, and the power dissipated in the pair of output transistors.
